DETAILED DESCRIPTION

[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a concealed floor drain comprises a concealed floor drain body 1 and a concealed floor drain sleeve 2, wherein the concealed floor drain body 1 is divided into a concealed floor drain pipe fitting 3 and a top cover 4, wherein the top cover 4 is provided with a plurality of water leakage openings 5, and the plurality of water leakage openings 5 ​​are in conduction with the concealed floor drain pipe fitting 3, and the lower end of the top cover 4 is provided with a plurality of tooth-shaped filter teeth 6 along the circumferential edge of the top cover 4, and the concealed floor drain pipe fitting 3 is provided with a plurality of protrusions 7 with the axis of the concealed floor drain pipe fitting 3 as the center line, and the plurality of protrusions 7 are evenly arranged on the circumferential outer wall of the concealed floor drain pipe fitting 3, the concealed floor drain body 1 is inserted into the concealed floor drain sleeve 2, and there is a gap between the concealed floor drain body 1 and the concealed floor drain sleeve 2.

[0019] When it is necessary to eliminate the hidden danger of water leakage in the bathroom through the hidden floor drain, at this time, the operator first inserts the hidden floor drain cover 2 into the pipe on the bathroom floor, and then fills the hidden floor drain cover 2 with a landfill height that is flush with the plane on the hidden floor drain cover 2, then paints the plane and inner side of the hidden floor drain cover 2 with waterproof coating, and finally inserts the hidden floor drain body 1 into the hidden floor drain cover 2. When in use, water can flow into the pipeline from the leakage holes on the top cover 4 and the tooth-shaped filter teeth 6 respectively. Foreign matter accumulated during washing, such as tired hair, is continuously blocked and filtered by the tooth-shaped filter teeth 6.

[0020] like Figure 2 and Figure 4 As shown, a plurality of the tooth-shaped filter teeth 6 are arranged from the inside to the outside as a first circle of tooth-shaped filter teeth 8, a second circle of tooth-shaped filter teeth 9 and a third circle of tooth-shaped filter teeth 10, and from the inside to the outside the bottom area of ​​the first circle of tooth-shaped filter teeth 8 is smaller than the bottom area of ​​the second circle of tooth-shaped filter teeth 9, the bottom area of ​​the second circle of tooth-shaped filter teeth 9 is smaller than the bottom area of ​​the third circle of tooth-shaped filter teeth 10, and there are gaps between the first circle of tooth-shaped filter teeth 8, the second circle of tooth-shaped filter teeth 9 and the third circle of tooth-shaped filter teeth 10.

[0021] By gradually reducing the bottom areas of the first circle of filter teeth 8, the second circle of filter teeth 9 and the third circle of filter teeth 10, this method can block small foreign objects such as hair accumulated when toilet users wash outside the outlet of the sewer pipe, thereby preventing strange smells after a long time.

[0022] like Figure 1 As shown, the four right-angle walls of several tooth-shaped filter teeth 6 are chamfered, and the cross-sectional area of ​​each tooth-shaped filter tooth 6 gradually increases in the direction approaching the top cover, the hidden floor drain sleeve 2 includes a sleeve 12, the top periphery of the sleeve 12 is provided with an annular first round cover 11, the edge of the first round cover 11 is provided with an outer box inclined sleeve side wall 14, and an annular second round cover 13 is provided on the upper end periphery of the sleeve side wall 14, the hidden floor drain body 1 is inserted into the hidden floor drain sleeve 2, the upper surface of the second round cover 13 is flush with the upper surface of the top cover 4, the tooth-shaped filter teeth 6 are abutted against the first round cover 11, the height of the hidden floor drain pipe 3 is lower than the sleeve 12, and the gap between the protrusion 7 and the sleeve 12 gradually increases from top to bottom.

[0023] By setting the four right angles of the tooth-shaped filter teeth 6 as chamfers, water can flow through more quickly without causing water accumulation due to excessive water conservancy. The inclined side wall 14 of the sleeve can facilitate the passage of water. When the hidden floor drain body 1 is inserted into the hidden floor drain sleeve 2, the upper surface of the second round cover 13 is flush with the upper surface of the top cover 4 to prevent the user's feet from contacting the hidden floor drain during use and causing injuries. When the gap between the protrusion 7 and the sleeve 12 gradually increases, water can flow through the floor drain more quickly to prevent the hidden floor drain from being blocked by water accumulation.

[0024] Working principle:

[0025] When it is necessary to eliminate the hidden danger of water leakage in the bathroom through the hidden floor drain, at this time, the operator first inserts the hidden floor drain sleeve 2 into the pipe on the bathroom floor, and then fills the hidden floor drain sleeve 2 with a landfill height that is flush with the plane on the hidden floor drain sleeve 2, then paints the plane and inner side of the hidden floor drain sleeve 2 with waterproof coating, and finally inserts the hidden floor drain body 1 into the hidden floor drain sleeve 2. When in use, water can flow into the pipeline from the leakage holes on the top cover 4 and the tooth-shaped filter teeth 6 respectively. Foreign objects such as hair accumulated during washing are continuously blocked and filtered by the tooth-shaped filter teeth 6. This method can not only efficiently perform the waterproof coating operation for the hidden floor drain, but also make the drainage smoother after the waterproof coating operation is completed, and will not easily cause blockage in the pipe after long-term use, and will not easily produce odor.

[0026] By gradually reducing the bottom area of ​​the first circle of tooth-shaped filter teeth 8, the second circle of tooth-shaped filter teeth 9 and the third circle of tooth-shaped filter teeth 10, this method can block the small foreign objects such as hair accumulated by the toilet users when washing outside the outlet of the sewer pipe, thereby preventing the emergence of strange smells after a long time. The four right angles of the tooth-shaped filter teeth 6 are chamfered to allow water to pass through more quickly, and water accumulation will not occur due to excessive water conservancy. The inclined side wall 14 of the sleeve body can facilitate the passage of water. When the hidden floor drain body 1 is inserted into the hidden floor drain sleeve 2, the upper surface of the second round cover 13 is flush with the upper surface of the top cover 4 to prevent the user's feet from contacting the hidden floor drain during use and causing injuries. When the gap between the protrusion 7 and the sleeve 12 gradually increases, the water can pass through the floor drain more quickly to prevent the hidden floor drain from being blocked by water accumulation.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
